Spain's Princess Cristina has been questioned in court in connection with a corruption scandal involving her husband's business dealings.

It was the first time in history that a member of Spain's royal family has appeared in court as the subject of a criminal investigation.

Her husband Inaki Urdangarin is alleged to have defrauded regional governments of millions of euros of public money.

The princess and her husband deny any wrongdoing, and have not been charged.

Analysis

Countless cameras and microphones were trained on the normally mundane back-entrance to the court, where the princess arrived.

A chorus of protest could be heard from the other side of the building.

For weeks Spain's lively TV and radio chat shows have analysed and speculated about every detail of the appearance of the king's daughter in court.

Would she walk the short distance down the ramp to the door of the court? Or would she be driven to avoid the cameras?

In the end she was driven to the door in a small dark grey Ford; there was no police escort for the final stretch of her journey.

Innocent or not, many believe this long-running, much-covered corruption scandal has caused significant damage to the credibility and reputation of the Spanish royal family.

The BBC's Tom Burridge in Madrid says the world's media will analyse every detail of this corruption case, which has already gone on for three years and made headlines in Spain on an almost daily basis.

Spain's royal household admits the case has damaged the reputation and credibility of Spain's royals, and, partly because of this scandal, the popularity of King Juan Carlos has fallen in recent years.

Hundreds of protesters chanting republican and anti-corruption slogans demonstrated near the court.

Closed-door hearing

Princess Cristina, 48, stepped from her car and walked into the court on the island of Mallorca without commenting to the waiting television crews.

King Juan Carlos's youngest daughter then faced a judge to answer questions relating to alleged fraud and money-laundering.
